This invention relates to a device for guiding roller hoods and is chiefly useful for all weather motor coaches in'which the hood can 1 be sid along guides provided laterally on the roo This device according to the invention is so arranged that the shocks reaching the guides from below are not transmitted to the hood. For this purpose the guided members are divided, the member carrying the hood being resiliently connected with thep'art of the guide which transmits the shocks. In this way breakages of the tilt hoops and the parts of the cover, are avoided. The invention further consists in providing two guiding tracks of which one is arranged above and the other below and a two-part guiding carriage, the two parts being forced in opposite directions against the guiding tracks by means of springs. I I

A further object of the invention is to press the guiding rollers on to the guiding tracks, so that they cannot rattle, but still can easily be made to slide without exertion.

The invention also provides a three track guide, one guide track and the other oppositely directed guiding track having a double track so that the guiding carriage can fit the curves of the guide more easily.

This is also to be further improved by the guiding rollers being mounted on their journals loosely with axial play so that at curves they can yield laterally and do not jam.

Furthermore an oblique position of the parts of the guiding carriage and jamming of the same is avoided by the parts being secured from turning relative to one another.

Further a particular advantageous and simple construction protected against dust and the like will be obtained.

A constructional example is illustrated in the accompanying drawings, in which Fig. 1 shows a motor omnibus with roller hood in elevation,

the uppe'rpart b of which forms one piece with the hoop foot c, the lower part at s guided with its hollow drical'part e. A spiral spring f presses the two parts apart. and thereby presses the four guiding rollers g of theupper part and the two track rollers h of the lower part of the guiding carriage against the tracks on the rail a. The guiding rollers, g and the the guiding carriage track rollers 72, are mounted'loosely on their journals without'any special securing means. m isatongue'whichprevents relative rotation of the two partsof the guiding carriage To two lateral eyes of theupper part of the guiding carriage are jointed two. folding levers i, which connect the individual hoops together and fold the hood material when the roller,hoodis.drawntogether. "The joints'of levers, which are 7 connected [together,are enclosed by hood protecting caps in order to prevent damage .to'the material of the hood. "Zis the chainfor opening and closingthe hood.f

What I claim is: r p 1. {A device for guiding track, a member guided upon the first guiding track, a member guided below the second guiding track connected with the .hood, a recess in the second member, a projection on the first member adapted to slide vertically in the recess of the second member. and.

helical spring in the recess adaptedto' press the two members apart and against their guiding tracks. 7 I

2. A device for guiding roller hoods comprising a guidingtrack, a second guiding track, a member guided upon the first guiding track, a member guided below the second adapted tracks and a tongue secured to one roller hoods comprising a guiding track, a second guiding supporting hoop, a set of rollers resting on the rail and vertically movable relative to the hoop, a second set of rollers under said overhanging portions of the rail, aspring interposed between the first set of rollers and hoop and upon which the hoop is supported to take up jolts, said spring also serving to urge the set of rollers apart whereby the two sets of rollerswill 'yieldably engage respectively the rail and overhanging portions;

4. A hood support for vehicles comprising a guide rail carried by the body of the vehicle, a hoop having a first set of rollers thereon, means on the rail to restrain them from upward movement, and a second set of rollers resting on the: rail and movable'towards and away from the firstset, resilient I means mounted between the second set of rollers and hoop andvoperative to yieldably support the weight of the hoop on the sec ond set of rollers to take up olts and to yieldably hold the first set engaged withthe rail.

5. A hood support for vehicles comprising a guide rail having upper and lower 1 tracks, a carriage movable.v along the rail,

two sets of guiding rollers .on the carriage engaging-respectively, the upper and lower tracks, a hood supportlng hoopresti'ng on said carriage and. spring means between an end of said hoop and the carriage and operative to resiliently suppoft the hoop through one set of rollers onthe lower track and take up jolts and also to holdthe other set of rollers against the upper track.

[6. A device for. guiding roller hoods of vehicles comprising a guide rail supported on the body of the vehicle, guide rollers normally resting on the floor of the vrail, a hoop, o

and resilient means between the guiding rollers and the hoop such that the weight of the hoop is transmitted through the resilient means onto the guiding rollers and thereby .to the body of the vehicle, and a play be tweenthe hoop and the guiding rollers of such size that it allows free up and down movement of the hoop against the action ofthe resilient means for taking 7 up jolts arising betweenthe body of the vehicle and the hoop. 7

In testimony whereof I afiix my signature.
